The DNR says 29-year-old Tyler Hall of Twin Lakes, Minn., had finished a run as part of the Jack Helgren Memorial Race near Clear Lake State Park on Saturday morning when he lost control of his snowmobile.

Hall had completed his run while traveling 75 mph when his snowmobile veered off the route and hit a snow drift. He was thrown from the snowmobile and slid about 100 feet on the ice.

Hall, who was wearing a helmet, suffered a broken collar bone. He was taken to a Mason City hospital, where he was being held overnight for observation.
